Fig. 22 shows the bell andthe operating mechanism therefor.` Fig. is a perspec-l tive view showing a shaft with various parts the amount .or value keys, 3 the special or department keys, 4L the cash drawer, and G the operating handle. In generalterms the form of the invention which is shown in the drawings may be said'to comprise a single key board of amount and department keys, register operating .mechanism cooperating with said keys, a series of independent counters arranged to be brought into connection with the (.)perating mechanism at will, amount indicators, special indicators, means for moving the operating mechanism by the cash drawer, and a lever handle for operating the mechanism independently of the cash drawer when so desired. The `amount or value keys 2, as shown in Fig. 5 of the drawings, are mounted in live horizontal rowsor banks of 9 keys each and each row is numbered in the usual manner, from 1 to 9 or 10 to 90 as the case may be. .The special or department keys which are twelve in number are mounted in a horizontal row or bank above the amount keys. The heads of the amountkeys upon which the designating numerals are secured or otherwise fixed are preferably round as shown, but the heads of the special or department keys are square whereby they may be readily distinguished from the amount keys in operating the machine. The counters as will be seen by reference to Fig. 1 are twelve in number and are arranged in fourvertical rows of three counters each. All of these counters except the lower o-ne in the extreme right hand tier may be saidto be independent of each other. The excepted counter, which registers the grand total of nine of the other counters, is4 arranged to be op erated simultaneously with any of the otherl counters except the paid out and charge counters which happen to be located directly above it in the same tier. The amount indicators, Figs. 1 and 11, are arranged above vthe counters in duplicate, oppositely-facing sets adapted to indicate at the back and front of the machine respectively the amount and character of the last recorded transaction. With this brief description of the several elements going to make upl the complete machine a detail description of the several mechanisms and considering these inthe order in which they naturally present themselves to the operator, the key board will be first described and its several connections.

The 'fey/ b0awZ.-'l`he key board or frame is (Fig. 2), in which all the keys are movably ,mounted in the order above enumerated comprises two parallel's'paced and connected l respective key shanks.

guide for said slide.

apertured plates 9 and 10 and spaced dividing webs 11 (Fig. 19) extending from' plate v10 about half of the distance toward plate 9 and provided with notched flanges 12 through which the key-Shanks extend. The latter' are preferably square in cross-section and besides passing througlrthe notched flanges 12 also pass through guiding apertures, formed in plates 9 and 10; each of said keys bein-g normally held in its outer position by a coil spring13 which surrounds its shank and bears against the respective flange 12 and a pin lll mounted in said shank. Each horizontal bank of keys including the special. bank, is provided with a detent rock-shaft 15 suitably journaled in the key board and having a series of rigid latch lingers or pawls 16 which are arranged to engage notches 17 and 1S formed in thc Each rod 15 is provided at its left hand end as shown in Fig. 8 with an arm 19. These six arms are engaged by pins 20 mounted upon a slide 21 which is movably secured by a. suitable slotand-pin connection 22 and 2?; on the left hand end of the key-board frame. The slide 21 is normally drawn downward by a coil spring 24 which connects it to the keyboard frame so that pins 20 normally tend to force the arms 19 downward and hold all of the pawls 16 in contact with their respective key shanks. From this structure it ren sults that when the keys are in their normal positions shown in Fig. 2 all of the pawls lie inthe notches 1S.` New, should one of the keys be depressed its respective pawl will be forced out of its notch 18 by the inclined wall of the same, and the shaft 15 carrying said pawl will thus be rocked ag'ainst a spring tension whereby when the pawl reaches the notch 17 upon a. full depression of the key it will immediately sna p into the same and thus latch the kei.7 in its` depressed position. lt will further he seen from the abovev that when anycne of the keys is depressed the slide 21 is first elevated and then as the key is linally depressed, is allowed to resume its normal position shown in Fig. 8. This peculiar movement of the slide is utilized to lock the operating mechanism against movement while a key is being depressed. To eilect these results the slide is provided with a lug 25 which when the slide is raised, passes into the notch 26 formed in an inclined locking slide 27, to lock the latter against movement while the lug remains in this notch, that isfwhile any key is being. one'aled. 'lhe locking slide is formed with a slot 2S through which one of a series of rock shafts 2S) passes to form The front end of said slide rests upon one of the pins formingthe slot-aud-pin connection between the slide 21 and the key-.board frame. The

ylower end of the locking slide is formed with rack teeth 30 which mesh with a segmental gear 3l fast to the main operating rock-shaft 32.

y As bet'ore explained, when any key is pressed, its transverse detent-sliatt l5 is thereby rocked, which, through its arm 19 and pin 20, raises the slide 2l and brings the lug 25 thereon into the notch 26 ot' the locking-slide 27. It', on the other hand, the locking-slide be tirst moved inward, the notch will be moved out of alinement with the lug, which will instead be adjacent the solid edge of the locking slide and therefore wheneyer the latter is displaced the slide 2l cannot be moved, and consequently no key can be operated. At each operation of' the machine as hereinafter described, the main operating rock-shaft 3i. is swung in the direction of the arrow (Fig. S) and the locking-slide is thereby moved inward, trom which it results that no key can be pressed after the operation ot the machine has commenced. The locking slide is arranged also to lock the counter-throwing shat't 33, hereinafter described, so as to prevent any counter' being thrown into engagementwith the operating mechanism except at the proper time. This is accomplishedby means of an upward eX- tension or arm 34 formed on the locking slide and carrying a lateral, inwardly-pro jecting pin 3T, which normally contacts with the downwardly-extending arm 36 fast upon the shaft The said arm is connected to a coiled spring 35 which normally tends to draw it rearward. So longl as the lockingslide is in normal position, however, the pin 3T locks the arm 36 in` the position shown in F ig. S and thereby prevents any movement of the counter-throwing shaft 33, and consequently prevents any ofthe counters from being thrown into 'engagement until the proper time. Indeed, the arm 36 is not un-.

locked immediately upon the beginning of movement of the locking-slide because it is still held in normal position by the .latch 33 which is pivoted upon one of the series of rock-shafts 39 and has a locking nose 40 which engages the correspondingr 'nose 4l .on the arm 36. Vfhen the locking-slide nears the end oit its inward movement, the pin 37 strikes the depending end of the latch 38 and rocks it so as to withdraw the nose 40 from engagement with the nose 4l, and thereby the counter-throwing shaft' 33 is unlocked. The counters, therefore, cannot be thrown into engagement with the registering racks hereinafter described until the locking-slide has almost completed its inner or rearward movement. "ln this manner the counter-operating racks, as will be presently described, are, given ample time to assume their' differential positions before the counters' can be thrown into engagement. When the slide 27, is returned to its forward position the ipin 237 again engages the arm 36 and forces the same forward against the tension of the counter-throwing spring 35 until the latch 3S again engages the shoulder 40 and holds the shaftl 33 in its set position shown in F ig. 8. i

lVhen a key has been depressed and locked in its operated position, it is necessary atter the registration has been made, that said key be automatically released, and to accomplish this result at the proper time I provide each oit' the shafts l5 at its right hand end with a rigid arm 42. (Fig. 4).- Each of these arms if' adapted to be struck and operated by a pin 43; said pin-being rigidly mounted upon a slide bar 44 which is mounted upon the key-board trame by a suitable slot-andspin. connection 45 and 46.

The v slide 44 carries a pivoted pawl 47 having a tam tace 43 and held in its normal position by a coil spring 49 connected thereto and to a slide bar 50 hereinafter described. The

cam tace ot this pawl is so located as to be engaged by flange 51a formed on the forward extension 5l of the transfer operating slide 52. The latter is formed with a slot 53 through which passes one of the rock-shafts Q9; the lower end of said slide being formed with a` curved slot 54 into which projects a pin mounted on 'the toothed full-stroke segment 5G which is fast to the main rockshaft 32.

rlhe above described parts are shown in Fig. 4 in their normal positions with the pin 53 in the forward end ot' the slot 54 and the tiange .3l in front of the pawl 47. When the machine is operated the full-stroke segment 56 rocks rearward with the shaft. 32 as hereinatter described and hus carries the pin out of the. slot :34, which action releases the 'transfer operating slide 52 and allows the same to be drawn rearward as tar as the length of slot will permit. As the trans fer operating slide 52 passes rearward the flange 51 pushes the pawl 47 aside until it has passed, when said pawl is drawnback to its normal position by its spring` 49. As the shaft 32 is rocked back toward the normal position the pin 55 again enters slot 54 and forces the slide back toward its nor mal position, which action causes the flange 5l to engage the cam tace 48 of the pawl 47 and torce the same with the slide 44 upward; thus rocking all of the shafts 15 and disengaging all of the pawls 16 from their respective key Shanks. The transfer operating slide further carries a series of anti-friction roller-studs 57 which are arranged as hereinafter described to engage and operate rigid arms 58 one of which is mounted upon each ot the rock-shafts 29 except the top most one. n

ln order to prevent the simultaneous operation ot two or more of the special keys 3,

l ,propicie each of said keys with a wing 59 ;A (Figs. land 19) which are adapted to passdownward and transversely through a slotted tube G0 containing a. series of small sliding cylinders 61 having` conical meeting ends. When one of the special keys is depressed it passes down between two of these cylinders by engaging their conical ends and forcing them apart and thus in the usual lmanner locks all the remaining special keys as'there is onlyenough free space in the tube lto allow the passage of one of the wings 59 between the cylinders. The entire keyboard is detachably secured in position so that it may be removed as a whole. The board may be attached in any suitable manner but I preferably secure the same by overlapping flanges as shown in the drawings. y

In the present machine the registering mechanism is unlocked and its operation begun by the depression of an amount key and a special key. The result is accomplished by means of the following locking devices.

lloc/tine docking {Zcvz'oes.-Eaeli of the amount keys is provided at its lower projecting end with a laterally projecting pin (32 which contacts with one of a series of arms each of which is fast to one of the aforesaid rock-shafts 39 as shown in Fig. 2. There is one of these rock-shafts coperat- 'ing with each horizontal row of amount keys and each rock shaft vis provided at its right hand end with a rigid arm G4 (Fig. 4). These arms are arranged to respectively engage pins (35 fast on the aforesaid slide bar 50 toraise' said slide when any one of the amount keys is depressed. The said slidebar 50 is mounted in position by being formed with elongated slots 66 through which two of the shafts 39 pass.

The slide 50 is normally held in its lower position by the aforesaid coiled spring 49 which connects it, as shown in F ig. 4 with the pawl 47. Mounted rigidly upon the slide-bar 50 is a small block or projection G7. which when the slide is moved upward, either passes in front of a pivoted release `pawl (i8 or contacts with its lowerJ end according to the posit-ion of said pawl. The release pawl GS is pivotally munted upon the upper' front end of a bell-crank lever 69 which'is in turn pivotally mounted upon a short shaft 119. The upper end of said lever 69 normally rests upon one of the shafts 2t) and is held thereon by a coiled spring 7l which connects the pawl (38 with a portion of the main frame. The upwardprojecting portion of `the release pawl GS 1s arranged to be engaged by a' pin 72 mounted on a crank-arm 73 which is fast on a rock-shaft 7l. This shaft 74 carries a series of rigid arms 75 (Figs. 3 and 10) which are engaged by pins 7 G mounted on the -shanks of the respective special keys 3. l

The drawer is released and the operation of the registering' mechanism started, by

swinging the bell-crank locking lever G9 upward, in a manner to be presently described. Byreference to the mechanism just referred to it will be seen how it is that the operation of both a -value key and a special key is necessary in order to move the bell-crank lever to eii'ect the drawer release, and it makes no difference whether the amount key is oper-- ated before theA special key or vice versa, or whether both the keys 4be operated simultaneously. If the amount key be pressed, the slide 50 is raised in the manner already described, thereby bringing the small block;v

or projection 67 up and in front of the lower end of the release pawl (3S. -lVhile the block then is in this raised position, or in other words, whe an amount key is depressed, the

i shaft 74 is rocked and the cr'anlearm 7 3 and the pin 72 carried thereby are swung downward and toward the rear, and Contact immediately with the upper end of the releasepawl. rlhe latter, however, cannot swing rearwardly, as already described, and the effect therefore, is to swing the bell-crank 69 upward, the pin 72 sliding down the front edge of the upper end of the release-pawl and the lower end of the release pawl sliding upward behind the small projection 67. As before stated, the swinging upward of the locking lever releases the cash drawer and starts the registering mechanism. Suppose now a special key were operated first. The crank-arm 73 and pin 72 would be swung rear vard, as alreadyv described, and as the block or projection '67 is entirely below the release pawl. the latter is free to swing on its pivot. rlherefore. the bottom edge of the lower end of the release-pawl is. brought squarelv into the path of the small projection G7. The subsequent operation of a cash key raises the slide 50 and the projection 6 7. The latter innuediately contact-s with the release-pawl and raises it, at the same time swinging the locking lever upward and releasing the cash drawer. The bell-crank locking lever GS) is further formed upon its lower arms (39 with a projecting arm 77 having an apertured flange 78. An L-shaped lever 79 is fast to one end of a rock-shaft S0 suitably mounted in the frame of the machine and is so locatedA that its free end passes through the aperture in the iiange 7S; a vsuitable enlargement or hook Sl being formed on the short limb of the L-shaped lever to prevent its disengageend of the rock-shaft 89 opposite from that Carrying lthe bell-crank 7 9 is provided with a rigid rearwardly and downwardly eXtendv scentof the pawl. The forward end of the pawl is curved tothe right to bring it on the opposite side of the lever 83. The lever 83 and pawl 84 are arranged to coperate with a pivoted latch-plate 86 mounted upon the back ofthe cash drawer 4t and normally drawn to the right by a coiled spring 87. (see Fig. 18) which lconnects said plate to the drawer. The latch-plate is further braced in position by a pin 88 so as to resist any strain brought to bear thereon by the normal tendency of the cash drawer to open. The upper end of said latchplate is formed with the notched upper end 89 which is normally drawn into a position to contact with the rear end of the lever 83 to prevent the cash drawer from opening. hen the shaft is rocked in the manner before described thefrear end of the-lever is elevated sufficiently to clear thelatch-plate and allow the cash drawer to open. When it is being closed, the bent 'front end of the pawl 84 enters the notch inthe upper end of the latchplate. As the closing movement continues` the right-hand edge of the upper end 89 ofthe latch-plate strikes the left-hand side ofthe pawl 84 and the latch-plate is thereby swung. to the left against its spring* 87 until itpasses back of the rear end of the lever 83, 'whereupon it promptly snaps into position behind the rear end of said lever and so as to retain the drawer yin its closed position. 'from the shaft 80 so as to project above a lug 88a formed on the slide 21 (Fig. 8). Now, when vone of the amount keys has been operated and then one of the special keys' is pressed or vice versa, the spring 82 will be compressed, as before described, to vmove the lever 79, but this movement will .not take place until the second key is operated, whether itl be amount or special key, has been fully depressed, as during the depression of the secon'd ykey the slide 21y will move upward, thus causing the lug 8?? to contact with theforward end of the le-` The lever 83 is extended forward the cash drawer until the operated special key has been depressed far enough to latch it -in its operative position. The cash drawer Il when released/is forced out of its casingbyv a coil-spring 90 interposed between the back of the drawer and the drawer casing in a manner well known in the art and needing no further description here.

Having now described the key board, its cooperating detents and the means for releasing the cash drawer in connection with the keys, next in order of description are the counter operating devices which are limited in their movements by the keys which act as stops therefor and thus permit the operation of said devices to a greater or less degree according to the value of the key depressed.

Counter operating devices-The counter operating devices comprise primarily a se- .ries of inclined rack bars 91, 91a mounted in the. main frame by means .of transverse shafts 92 which pass through elongated slots 98 formed in said bars; the bars being suit` ably spaced by sleeves 94 mountedy on said shafts between them. These bars are a1'- ranged in four groups or tiers of seven bars each so that each group will be capable of operating the three counters ofeach respective tier, the arrangement being best shown in Fig.4 1. Counting from the right-hand side, the rst five rack bars of each group are registering racks 91. rl'he sixth and seventh rack bars of each group are the transfer racks 91a. rackbar of each group represents the units of cents bank of keys, the second bar from the right in each group represents the tens of cents, the third bar represents the units of dollars and so on throughout the first live bars of each group counting from the right. thus have four bars (one in each group) which represent units of cents, four which represent tens of cents, and so on through the several denominations. lVith this structure it becomes necessary to couple the cor responding bars so that they 'are moved in unison. To accomplish this result .each of the units of cents bars meshes with a segmental pinion mounted upon the uppermost one of a series of transverse rock shafts 29, for which see Fig. 14. Each segmental pin-v ion 95 is movably connected to its shaft 29 by a radial pin 97 fast to said shaft and which projects through an elongated .slot 98 formed in the hub orsleeve ofthe pinion. ByV this structure thev pinion- 95 may ,have a limited movement independent vof the shaft 29 upon which it is mounted. Thislimited and independentmovement is utilized in effecting the transfer, as will be presently de scribed. Each of the pinions is con-` nected `to its respective pin 97 `by a coiled spring 99 which will norm all y-draw the forward end of the pgin against one sidev of the (See Fig. 8.) The right-hand slot 98. As shown in Fig. 2 ofthe drawings, the pin 97 is resting against the opposite Wall of the slot 98 from 4that against which it would normally rest because of the 5 stress of the spring 99. While in this posi- -tion it Will be observed that the pinion 95 may move forward the distance of one tooth under the impulse of the spring 99 but it will be arrested by the pin 97. In order to 0 rotate the registering shaft 29 and thus cause the forward end of the pin 97 to assume the position shown in Fig. 2, I provide the aforesaid arms 58 and the roller studs 59 which are carried by the transfer-operating slide 52, Fig. 4. These parts, after the rack-bars 91-have been returned to normal position, impart a slight additional rotary movement to the registering shafts 29 just at the end 'l ofthe operation of the machine. This filial movement of the shafts is of course independent of the pinions 95 Athereon because the latter are in engagement with theirrespective registeringracks, and at this time these are in normal position and prevented from further upward movement by their posite sides of the slots 98 from those With Which they Were before in contact.l With theisprings 99 thus under tension, if one of the racks is at this time released by its stop lever, its coperating spring 99 immediately turns the segmental pinions 95 forward and consequently raises the engaged rack-bar. The arrangement is such that the rack-bar can only be thus raised far enough to move theK engaged registering Wheels one notch.

In this-manner, as will be more fully de-l scribed hereafter, the transfer is effected.

It Will be seen from the foregoing thatas the registering racks 91 mesh witli/ the pinions 95, the descent of one of said bars will cause its pinion to be rocked and thus .rock

the shaft 29 and all the three' other pinions mounted thereon, which of course will result in all the racks meshing with said pinions being'correspondingly moved. As all of the shafts 29 and their immediately coperating parts are similar in construction the above descriptionwill sutiice for all. Each of said shafts 29 is further provided With a series of registering stop arms 100 arranged in graduated order to permit of a greater or less movement of said shaft, as best shown 1n Figs. 13 and 14. When one of the amount keys is depressed, the shaft 29 of'its respective bank is released, and the simultaneous descent of the four rack-bars which meshA with the pinions on this sliaft, eauses the shaft to rotate until one of the arms 100 'contacts with the shank of the depressed kev. Vhen one of the registering shafts 29 is released, as above described, a spring 96a, one

i by the restoring frame.

of which is located upon the left-hand endv of each shaft, immediately turns the released registering shaft rearward, see Fig.

17. Near its left-hand end each registering shaft is provided with a rigid arn'. 101 and the spring 96a of each registering shaft is connected at one end to the pin 102 on the arm 101 and at the other to some fixed portion of the frame of the machine. See Fig. 10. The spring 96a by turning the registering shaft turns also the segmental pinions on the shaft, and assisted by gravity, and other springs, causes the racks in engagement with the pinions on that shaft, to drop as the shaft turns, until one of the graduated stop-arms 100, also on the registering shaft, contacts with the shank of the depressed key. The distance the racks descend is of course proportionate to the value to be registered and according to the numerical value of the amount key pperated.

Inv the present'embodiment o-f the invention, after the ,racks have dropped to their lowermost position, the counter is automatically thrown intoengagement therewith.

Upon the subsequent closing ofthe drawer. y

or operation of the handle 6 the restoring frame 112, to be hereinafter described, engages all the displaced racks and raises them almost to normal position. Then the transferoperating slide 52 turns .the registering'shaftsl 29 a short distance farther, which has the effect to turn the segment-pinions to raise the racks to normal position; that is, a little beyond the point to which they were carried In this position they are supported by the transfer-operating slide 52. As soon as the cash draweris released, bothf supports are `withdrawn from the registering-rack-bars 91|; that is the restoring frame and the` transfer-operating slide both fall.

tially in normal position, being held by the engagement of the 'hooked latching armsA 103 over the ends of the arms-101. On the other hand, if an amount key has been pressed, its coperating-shaft 39.is thereby rocked, which throws the-hooked latching arm 103vaway from the arm 101 and thereby the coperating registering shaft 29 is unlocked and the four racks which are in connection therewith, 4being unsupported, fall with the registering frame.` Thus each `reg-- .istering rack 29 is lockedagainst registering movement until a key ``1n vits coperatingl `bank 1s operated.

The latch arms 103 are not secured rigidly upon the shafts 39, but'instea'd, as shown in Fig. 17, the hub ofthe latching arm is slotted vand the pin passing through the shaft 39 projects into the opposite slots in the hub. In this manner the shaft 39 may be rocked a considerable distance without@z raising or .unlatching the arm 103. It re If no amount key has been l l operated, all of the racks remain substan- Lerares leased in fact until the amount key has been pressed in far enoughfor the detent pawls 16 to engage the key shank and thus lock' the keys in their inner position. The present machine is constructed to operate only after one of the special keys has been operated and in order to preclude 'any possibility of the machine being otherwise manipulated each of the shafts 29 is provided with an additional locking device consisting of a slide-plate 107 which is formed witha series of hooks, 108 that project over the pins 102 when said plate is in its normal position shown in Fig. 8. This plate is suitably slotted to permit the passage et' two of the shafts 39 therethrough to act as guides and supports therefor. The upper end oli' the slideis provided with a `pin 100 which projects into a notch 110 formed in an arm 111 'fast to the special key shaft 7d as shown in Figs. 8 and 10. The shaft 74, as before described, is operated or rocked' upon a depression of any one of the special keys and when so rocked it elevates the arm 111 and thus moves the slide 107 upward to such an extent that the pins 102 are clear of the hooks 108 and the shafts 29 are thus free to rotate in the manner before described. The locking plate 107 is simplyl an auxiliary locking means and is provided, as before stated, to prevent fraudulent manipulation of the machine.

The registering rack-bars 91 (F ig. 2) are raised toward their upper normal position by the restoring frame 112, fast upon a transverse shaft 113 and which engages shoulders 1111 formed on said rack-bars. The restoring frame is supported in position and operated by two cams 115 which are `fast upon the shaft 32 near its opposite ends and engage anti-friction rollers 116 mounted upon the respective side bars of said frame as shown in Figs. 3 and 8. The connections for rocking the shaft 32 at each operation of the machine will be hereinafter described and for the present it will suffice to say that the shaft and cams 115 are rocked back and then forward at each of such operations to first drop the restoring frame and to then raise it to the position shown in Fig. 2. Said frame has a uniform stroke or travel at every operation. When'the registering racks are unlocked and released, their descent is assisted by the coiled springs 117 each of which is connected ai' one end to a pivoted lever 118 mounted on the rigid. transverse shaft 119. (See Fig. There are of course as many of the levers 118 as there are racks in each of the four sets. Or in other words. there are seven of these levers and each is formed at its forward end with a downwardly extending nose 120 which normally rests upon the restoring frame. In like manner, there are seven of the springs 117. There are also seven of the indicator-operating levers 122, which are pivoted at their front ends on theshai't 119, and carry each a roller 121. Each spring 117 is secured at. its lower end to one 'of the levers 118 and at its upper end, for convenience, to a journeled pin on its respective roller 121. There are also pivoted upon the shaft 119, seven intermediate levers 1237 see 23, whieh are employed to transmit the graduated. movement from the registering racks to the indicator-operating levers 122. Upon the rear end of each intermej diate lever rests one oi the rollers 121 which are carried respectively by the indicato operating levers, F ig. 3. The front end, 124, of each intermediate lever is slotted as at 125 so as to straddle a pin 126, one of which is carried by each of seven of the` registering racks. In front of its fulcrum each lever 118 is provided with a lip 127 which normallysextends over and above the upper edge of the front end of its adjacent and cooperating intermediate lever. There is, however, enough space between the under edge of the lip and the upper edge of the intermediate lever so that the latter can have a slight independent movement when' its registering rack is moved upward in effecting the transfer. In other words, when the' rack is moved upward an extra tooth to eliect the transfer, the said lever swins upward with it and the said space is just sui- -cientso that the intermediate level will not in so doing move the lever 118. When the restoring trame drops, it a key in the unitsof-cents bank has been operated, the four units olf-cents registering racks also drop. lf a. key in the' tens-of-cents bank has been operated then the four tenspf-cents registering racks drop, etc. When any of the racks drop, the front ends 124 of their cooperating intermediate levers 123 are of course swung downward. As soon as the Vrestoring :frame begins to move downward all of the levers 118 immediately drop down until their lips 127 strike their :Gespective cooperating intermediate levers. If a certain rack has not'been released, its cooperating lever V118 moves no farther.- .On the other hand, if the registering rack has been released, its cooperating lever 118 assists in its fall `by pressing upon its cooperating intermediate lever. The upward movement of the restoring frame of course returns all the levers 118 to normal position.

As alreadyv stated, -the rollers 121 of the indicatonactuating levers-122 are in the path of movement of the rear ends of the intermediate levers respectively. Each ine dicator-operating lever is pivoted at its rear end to one of `the several indicator-operat ing racks 187, the*y latter mesh directly lis with pinions on their respective indicators. A more specific description of these parts will follow, but sufficient has been said to show how the differential or graduated movement of the registering-racks is transmitted to the. respective indicators to indicate any amount registered. Then the restoring frame commences its return or ascending movement it first contacts with the noses 120 of the levers 11S, and raises them.

shafts 129 and a series of counter-wheels ner to be v.counter-wheels are held agalust any retro- 130 mounted loosely on a counter-shaft 131 journaled in the aforesaid frame 12S, as there are twelve counters there are of course twelve counter-shafts. Each of the counter- Wheels is provided with a pivoted springpressed pawl (Fig. 3%) which is adapted to engage a longitudinal groove 133 in the shaft 131 so that. when said shaft (Fig. 16) is rotated by a thumb nut 134 fast to one end thereof the wheels will be picked up and( returned to zero in a manner well known in the art-. Each of the counter-wheels is further provided with a pinion 15:35 and a transfer cam disk 130 (shown in broken lines Fig. 3). The pinions are adapted to be thrown into mesh with their respective racks when the cminter-fran'ie 12S is rocked in the manhereinafter described. The

grade movement by spring-pressed retaining pawls 137 mounted in the frame 128 and engagingthe respective pinions. As all of the counters are practically of the same construction and operation one only will be described as this description will suffice for all.

Each counter frame 128 is provided with a rearwardly extending counter arm' 138 formed at its rear .end with a slot 139 into which projects an angular offset 140 mounted on one of a series of twelve counter throwing bars 141, that. is, one for each counter. Said bars are guided at their upper ends by a transverse .'rod 142 'which passes through elongated slots 143 formed .in said bars. The lower end of each counter-throwing bar is pivotally connected to one of a seriesof twelve coluiter-throwing levers 144 and is` also provided with a triangular gravity pawl 1,45. Each counter-throwing lever 144 is formed at its forward end with the elongated slot 146 having a shoulder 147 `upon a transverse shaft 153.

which shoulder is adapted to be forced into a V-shaped groove 148 formed in' the counter-throwing shaft The shoulder :147 of each lever normally lies out. of the groove 148, as shown in Fig. 3, but when one of the special keys is operated 1t slides under the forward enlarged end' of its respective counter-throwing lever and raises it thereby forcing the shoulder 147 into the V-shaped groove '148. Then the counterthrowing shaft 33 is now rocked by its c-ounte1.throwing spring 35 the counterthrowing lever 144 will be swung upward and thus force its counter-throwing bar 141 upward7 which operation will result in the rocking of respective counter frame to bring the pinions of the counter carried by this frame into mesh with their respective racks as shown by the middle counter in Figs. 3, 8 and 10.

It. will be seen by reference to the drawings and previous description that while there are only tive banks of amount keys there are seven rack bars in each group. Five of these rack bars, as has been previously explained, are controlled by the respect-ive banks of keys, whilethe sixth and seventh bars in each group counting from the right are practically free of any control of the keys and are simply to effectv the transfers between the fifth and sixth, and sixth and seventh counter wheels yof each counter. It therefore becomes necessary to provide some means for moving the sixth and seventh bars of each group upward to effect the transfer when the latch which holds thebar in its normal position has been tripped in a manner to be hereinafter more fully described. This means comprises in each instance a coil-spring 149 (Fig. 10) which connects its respective transfer rack to the upper one of the guiding shafts 92. The slots 92a through these transfer racks are only of a length to allow --the racks to rise the space of one tooth and they preventany descent of the racks below their normalposition. 'By this means lthe sixth and seventh bars of'each set are normally held in the position in which the regularoperating racks are shown in Fig. 10, but at the same time are free to ascend the dist-ance of one tooth in order to effect transfers..

Each of the racks 91 and 91a is formed at its upper end with a shoulder 150 (see Fig. 3) which shoulder normally contact-s with the .noses 151 formed respectively on the series of stop levers 152 which are pivoted ver is formed at its lower end with a foot 154 which normally rests upon'the upper end of a bell-crank trip lever 155, to hold said stop lever 152 in its normal position. The trip levers 155 are pivoted upon the upper one of two transverse-shafts 1 56 which 'pass through slots 157 formed in the sliding ISU 20 and thereby force transfer-plates 158. There are twenty-four transfer plates; that. iS to say, six to each ofv the four groups of counters. The lower end of each of the trip levers 155 is provided with a pin 159 which projects into a cam slot 160 formed in its respective transfer plate 1'58. Each transfer plate is further formed' with a plurality of forwardly projecting transfer fingers 161 which, when the wheels, say for example the units of cents,

has made a complete revolution its cam will contact withpne of the transfer .fingers 161 the plate 158 upward. This upward movement causes the walls of the cam slot 160 to swing the pin 159 forward and thus rocks the trip lever 155 to disengage its upper end from the foot 154. When this disengagement takes place the stop lever 152 swings forward at its lower end thus removing the nose 151 out of the path of the shoulder 150 of its respective registering or transferrack. If the tripping or unlocking of the stop-lever 152 occurs when its respective registering rack is below normal position, the latter is returned to and beyond normal position far enough to effect the transfer on its engaged registering 35 wheels. as will be readily understood.' As

before'stated, the transfer movement is 1m vparted to the rack by its transfer spring 99. If the tripping or releasing of the stop-lever 152 occurs while its cooperating registering rack is in lnormal position, the latter-is immediately thrown up by its registering spring the space of one tooth, ahd the transfer is thereby accomplished. After any of the transfer slides 158 have been raised they t5 are returned to its normal position by the re.- setting rock-shaft 162 suitably mounted in the main frame and formed with a V-shaped groove 163 into which a shoulder 164 of the .slide is projected when said slide is elevated. Y

After the transfer' has been effected, the resetting shaft 162 is rocked which causes one of the walls of the V-groove to engage the shoulder 164: and force the 'transfer slide down. This downward movement of the .slide causes the trip lever 155 to again assume its normal position 'and as the stop lever 152 has meanwhile been reset as hereinafter described, the saine will again b ecome .locked with its nose 151 in the path 6o of the shoulder 150. The resetting shaft 162 is rocked to return the transfer 'slides or plates by means of a rigid arm 165 fast thereon as shown in Fi 3 and which projects between two space lugs`166 formed 0n 65. a slide 167 which is suitably mounted on the l any of the stop levers 152 which as are registered upon the 'thrown counter-throwing leversdl are arranged' to 180 main frame and is provided near its lower end with two similarly spaced lugs 168. lAn arm 169 fast to the shaft 32 is adapted, when the shaft is oscillated, to contact with the upper lug 168 and thus raise the slide 167; the lower lug 168 meanwhile passes under the arm 169 so that when theshaft 32 is rocked back again the arm will strike the lower lug and return the slide 167 to its normal position. The stop-levers 152 are 75 all returned to their normal positions by a resetting yoke which comprises'two pivoted arms 171 anda connecting cross bar 170. This cross bar as shown in Fig. 3 is normally free of the rear faces of the noses 151 so 80 that when one of .the stop-levers is released, it isfree to pass forward at its lower end .under the impulse of a coiled spring 172 which surrounds the shaft 153 and bears with its opposite ends one against the stoplever and the other under the cross bar 170. The tension of the springs 172 normally tends to throw the stop-levers out of the positions shown in Fig. 3 whenever said levers are relieved of contact with the levers 155. One of thearms 171 of the resetting yoke is provided with a rearward extension 173 (see Fig. 6) which is pivotally connected to a'link bar 174 which in turn is connected to anv arm 175 rigid with the restorg5 ing frame 112. By this means the yoke 171 is thrown forward upon the downward stroke of the restoring frame 112 to reset have been previously tripped. The operation also re- 100i' sets the registering and transfer racks.

The preceding description of the method and manner-of throwing the counters into engagement 'with the registering and transfer racks according to the special key de- 105.

pressed applies to allof the special counters except the grand total counter, which is to receive all of the registrations except such charge or paid out counters. The throwing lever- 144- (Fig. L1) of the grand counter is not arranged to be swung upwardiat its front ends lb any special key, but is thrown into operative position through the medium of a rock-shaft 177 which carries a rigid 'arm lys 178 provided with a pin 179. This pirr 179 projects into an elongated slot 180 formed in a projection 181 of the throwing lever 144a of the grand total counter. The shaft 177 .is provided with a series ofarms 182 120 which extend above the respective levers .111.4 of the remaining special counters excepting thai charge and paid out counters. Now, when'one of the special counter-throwing levers 14:4l is raised by the operation of 125 its special key, it also raises one of the arms 182 and thus rocks the shaft 177 with the result that the grand total counter will be into operativev position.
